Dual extruders

[bubbasnow]

yea i was doing that, i get tons of oozing

[artexmg]

Because of the narrow opening in the stock Rostock MAX platform, I made my dual E3D adaptor place the E3Ds as close together as possible. That way the two bowden connectors actually fit through the platform...barely. I actually screw in the bowden's and align their edges *before* attaching the mount to the platform. It works although I need to make an alteration to my design for adjusting the height of one of the extruders because my 2nd extruder nozzle is a few tenths of a millimeter above the glass when the other one is touching the glass .

For anyone interested, here's the link to my mount for 2 E3Ds: http://www.thingiverse.com/thing:217662

Thanks for the desing! I have my own copy now; thanks for the tip of screwing it *BEFORE* attaching ... hehehe ... simple, but works!

oh, by the way, would you, please, share the X and Y offsets for E0 and E1?

I set mines :

E0 X=-10.83mm Y=6.25
E1 X=10.83, Y=-6.25

Thanks!

I modified the extruder offsets in the firmware (I was using 0.83 at the time). I used EXT0_X_OFFSET=-1000 and EXT1_X_OFFSET=1000 which basically sets them at -12.5 mm (80 steps/mm) and +12.5 mm.

Here is my copy printed and mounted (already properly credited in Thingiverse, of course )

As per the alignment problem, I added springs between the platform and the adaptor, so I was able to level the two hot ends easier.

Already had my first two color printing today (2 am !); double extruder is just so amazing!

Nice! Where did you get the springs and did you put them on all 4 screws?

I got an assortment box from amazon http://www.amazon.com/Neiko-Steel-Sprin ... y_hi_img_z" onclick="window.open(this.href);return false;
I put only 3 and worked fine. Maybe with 4 you have more control, but 3 is less screws to adjust. I guess even two should work.

Attached you will find my latest configuration and pin file... note that I also changed some other settings like turning off the beep (did it every tool change) and the preheat temps. If you find differences from what was posted please share back with the community so they too can run the duals
Note your offsets may be different depending on how you set yours up

Configuration.h

pins.h

In Repetier host go to config --> prninter --> number of extruders = 2

In slic3r endure you have it set to 2 extruders in printer settings and put in your offsets as well

Also here is what I have for my Start G-code in slic3r under printer settings --> custom G-code. This is because if you start switching between t1 and t2 when its homed the height gets messed up and will hit the bed. Having the tool change lower then home will allow it to switch around properly

G28 ; home all axes
G1 Z270 F500 ; brings to a safe zone to switch T0 and T1

Good luck....

When I try to verify these files I get the following error "WRITE(PS_ON_PIN, (POWER_INVERTING ? HIGH : LOW)); " "Commands.cpp:770: error: 'POWER_INVERTING' was not declared in this scope"

Any idea what I need to do to fix this?

Hi Guys,
I used the setting below and when I verified the changes in Repetier I this error.

alright i have it wired like this

from default 7 -> 8 because it was stopping extuder 2 from heating.. heater_2_pin was also 7 so i think there is a conflict.

make sure the drive is enabled in configure.h also

Code: Select all

#define MOTOR_CURRENT {175,175,175,200,200} 

then i connected RH and setup the printer with 2 extruders, and updated the eeprom and made both extruders the same.

now i can control them all

[dpmacri]

That Configuration.h file appears to be missing things. I'm not sure why -- BubbaSnow will have to answer that

[Eaglezsoar]

Wow, thanks for posting your config. That should help people implementing what you did.
With the kind of info you are posting it would be difficult to fail.

Hi Guys,
I used the setting below and when I verified the changes in Repetier I this error.

Any idea what's wrong?

What FW are you running?

[grimmindustries]

Repetier-Arduino 1.0.5

I've only loaded a few setting at a time and have avoided the error so far, but when I turn on my RostockMax the temps read correctly on the printers screen, when I connect from my laptop the second extruder jumps to 70 degrees even though it's not on. I am also having a problem with the cold extruder, no matter how many mm I set it to extrude the motor just keeps turning until I turn off the printer.

[bubbasnow]

Repetier-Arduino 1.0.5

Sorry i ment what Firmware is your RAMBo on?

[grimmindustries]

0.83 I believe.

[bubbasnow]

0.83 I believe.

those settings are valid only for .91 your going to have to upgrade if you want to use them as is

[grimmindustries]

Thanks, I'll try updating it.

[grimmindustries]

How did you get the firmware update?

0.83 I believe.

those settings are valid only for .91 your going to have to upgrade if you want to use them as is

[grimmindustries]

Never mind I realize that was a very stupid question.

[Ascensi]

Hi Guys, just successfully duel printed with my Kraken! No issues, well except for length of retraction I still have to adjust - I have volcano kraken hybrid! With the default calibration block in MatterControl it would normally take 35 min with the standard setting with a .3mm nozzle and the Volcano reduced that to 10 minutes with a .6mm layer height.

If anyone wants to use their duel printing for color and not just support I discovered that you would have to edit/duplicate your mattercontrol material and assign it to material 2, and in the slice presets editor add general>support material>support material extruder (set to 2)

Then add general>support material>support interface extruder (set to 2) <-- I'm not sure if this line needs to be added to the editor but it works fine anyways. You can set your single temp in here for your second extruder.

I wish there was a more thorough guide on matter control wiki for color/support material printing - here is a link with the limited Matter Control instructions http://wiki.mattercontrol.com/Multi_Extrusion

In repetier firmware I've enabled ditto printing but I haven't discovered how to extrude on the same model at the same time.. has anyone else made this feature work?
